The accumulating rain is resulting in street and roadway flooding throughout the area.

The strongest wind gusts have moved out of the Valley, but the rain will continue to be an issue throughout the afternoon and evening hours, First Alert weather team chief meteorologist Mark Finan said.

The National Weather Service issued an urban and small streams flood advisory until 9:45 p.m. for Amador County, Calaveras County, western El Dorado County, southwestern Nevada County, western Placer County, Sacramento County, San Joaquin County, Stanislaus County, southeastern Sutter County, western Tuolumne County, Eastern Yolo County and Solano County.

A flash flood warning has been issued for the parts of El Dorado and Placer counties burned during this summer's King Fire.

Wind gusts that reached up to 40 mph knocked down several trees and power lines in the Sacramento area earlier in the day.

In Davis, nearly 3,000 people lost power and about 900 customers were in the dark in South Sacramento, according to SMUD. Power was restored to nearly all customers in that area by about 9 a.m.

The storm pounded the Bay Area this morning, leaving more than 100,000 customers without power.

The utility's online map showed lights out over thousands of square miles, from Humboldt near the Oregon border to Big Sur on the Central Coast.

The storm also resulted in about 200 flight cancellations at San Francisco International Airport. At least two of those flights were headed to Sacramento.

High winds also canceled some ferry service east of San Francisco. At least 10 ferry departures around the region were canceled Thursday due to weather conditions, the San Francisco Bay Ferry reported on its website.

Wind gusts were also strong in the Sierra during the morning. KRNV in Reno reported that at least one airline -- Southwest Air -- canceled all morning flights (seven) out of the Reno-Tahoe International Airport.

The National Weather Service says some parts of Sonoma County got 9 inches of rain overnight. Venado, about 12 miles west of Healdsburg, got 9.04 inches.

The streets near downtown Healdsburg were about two or three feet under water.

At a Safeway grocery store, teenagers drove trucks through a flooded parking lot, trying to make waves for kayakers playing in front of the store. Grocery shoppers, meanwhile, trudged through water to get supplies.

Only a handful of schools in the Sacramento area closed their doors Thursday, including Jesuit High School, St. Francis High School and the Waldorf School in Fair Oaks.
